Except for brownies where you melt the chocolate and butter in the microwave then add the dry ingredients, I think most baking calls for at least 2 bowls-- one for wet and one for dry. Would 2 bowls be ok?

Thanks all! As noted in my response to drbabs, I actually don't mind if there is more than one bowl involved. I should have expressed my question differently. What I'm really looking for is something quick and easy that's new for me and a favorite for you.

I like to make it in a Pyrex cake pan so it looks nicer than in a metal one. I leave it in there, &just ice the top. OR I stir in chocolate chips or scatter them in top before baking & forget the icing altogether. One time I held a cut-out of a Christmas tree over the top & dusted over all with icing sugar..I'm a big fan of the quick & delicious!
